The Seattle Seahawks had great success signing veteran defenders on the cheap last offseason. They are trying the strategy again.

NFL Media Insider Ian Rapoport reported Thursday defensive tackle Kevin Williams has agreed to terms with the Seahawks on a one-year deal, according to a source informed of his plans. He chose them over the Patriots, who he also visited, and a return to the Vikings.

The news echoes Seattle's moves to bring Cliff Avril and Michael Bennett last year aboard in some respects. Both were players who sat on the free agent market for a while and came to Seattle at a bargain rate. Williams, who openly contemplated retirement this offseason, is at a different stage of his career than Avril and Bennett.

It's a great move for Seattle. Williams will provide depth in the middle, likely in a rotation behind Tony McDaniel and Brandon Mebane. Williams had over 700 snaps in Minnesota last year and was still an effective starter. The Seahawks could get even better play out of him by keeping him fresh coming off the field.

The Seahawks have been experts at finding value where other teams don't, whether in the draft or in free agency. Williams could turn out to be another savvy move.
